One thing is for sure, it irritates me to no end that all bar soaps fall apart when there’s still plenty of soap crying to be used. Unfortunately at this point they become unusable. So…I save my soap pieces and when I have enough to make at least couple of bars I rebatch them.
Here’s how I do it.
I found an old copper pot at Goodwill, that I use only for this purpose. I broke the soap into smaller pieces and put them in the pot with water on very low heat. (Don’t leave the pot while it’s cooking, it will become very hot and thicken quit quickly!!!) The soap pieces can also be shaved using a hand grater or a food processor, which will give the rebatched soap a finer consistency. Using bigger pieces of soap make the new bars a little more rustic.
Continue adding water and stirring (I found a wooden spoon works best) until you get the consistency of thick mashed potatoes. You can also take this opportunity to add a touch of food coloring and/or essential oils for fragrance. (Essential oils can be found at most any craft store).
I know this seems like a lot of work. But to me it’s more about recycling and not wasting.
Happy soap making~Bam
